1、及時(shí)發(fā)現(xiàn)問(wèn)題，檢修內(nèi)回流泵就可以了。 2、內(nèi)回流已經(jīng)導(dǎo)致氨氮升高，濟(jì)南氨氮菌廠家，檢修內(nèi)回流泵，停止或者減少進(jìn)水進(jìn)行悶爆。 3、硝化系統(tǒng)已經(jīng)崩潰，停止進(jìn)水悶爆，如果有條件，濟(jì)南氨氮菌廠家、情況比較緊迫可以投加相似脫氮系統(tǒng)的生化污泥，加快系統(tǒng)恢復(fù)。氨氮是指水中以游離氨（NH3）和銨離子（NH4+）形式存在的氮。濟(jì)南氨氮菌廠家</p><div style="width:100%;text-align: center;"><img

② 吹脫法，吹脫法的基本原理是氣液相平衡和傳質(zhì)速度理論。將氨氮廢水PH調(diào)節(jié)至堿性，此時(shí)銨離子轉(zhuǎn)化為氨分子，再向水中通入氣體，使其與液體充分接觸，廢水中溶解的氣體和揮發(fā)性氨分子穿過(guò)氣液界面，轉(zhuǎn)至氣相，從而達(dá)到去除氨氮的目的。常用空氣或水蒸氣作載氣，前者稱為空氣吹脫，后者稱為蒸汽吹脫。濟(jì)南氨氮菌廠家</p></p><br
